Field experience with the 8-HPV-type oncoprotein test for cervical cancer screening among HPV-positive women living with and without HIV in LMICs.

Overexpression of HPV-oncoproteins E6 and E7 is necessary for HPV-driven cervical carcinogenesis. Hence, these oncoproteins are promising disease-specific biomarkers. We assessed the technical and operational characteristics of the 8-HPV-type OncoE6/E7 Cervical Test in different laboratories using cervical samples from HPV-positive women living with (WLWH) and without HIV. The 8-HPV-type OncoE6/E7 Test (for short: "OncoE6/E7 test") was performed in 2833 HIV-negative women and 241 WLWH attending multicentric studies in Latin America (ESTAMPA study), and in Africa (CESTA study). Oncoprotein positivity were evaluated at each testing site, according to HIV status as well as type-specific agreement with HPV-DNA results. A feedback questionnaire was given to the operators performing the oncoprotein test to evaluate their impression and acceptability regarding the test. The OncoE6/E7 test revealed a high positivity rate heterogeneity across all testing sites (I2: 95.8%, p < .01) with significant lower positivity in WLWH compared to HIV-negative women (12% vs 25%, p < .01). A similar HPV-type distribution was found between HPV DNA genotyping and oncoprotein testing except for HPV31 and 33 (moderate agreement, k = 0.57). Twenty-one laboratory technicians were trained on oncoprotein testing. Despite operators' concerns about the time-consuming procedure and perceived need for moderate laboratory experience, they reported the OncoE6/E7 test as easy to perform and user-friendly for deployment in resource-limited settings. The high positivity rate variability found across studies and subjectivity in test outcome interpretation could potentially results in oncoprotein false positive/negative, and thus the need for further refinements before implementation of the oncoprotein testing in screen-triage-and-treat approaches is warranted.

Performance of standardised colposcopy to detect cervical precancer and cancer for triage of women testing positive for human papillomavirus: results from the ESTAMPA multicentric screening study.

BACKGROUND: Colposcopy, currently included in WHO recommendations as an option to triage human papillomavirus (HPV)-positive women, remains as the reference standard to guide both biopsy for confirmation of cervical precancer and cancer and treatment approaches. We aim to evaluate the performance of colposcopy to detect cervical precancer and cancer for triage in HPV-positive women. METHODS: This cross-sectional, multicentric screening study was conducted at 12 centres (including primary and secondary care centres, hospitals, laboratories, and universities) in Latin America (Argentina, Bolivia, Colombia, Costa Rica, Honduras, Mexico, Paraguay, Peru, and Uruguay). Eligible women were aged 30-64 years, sexually active, did not have a history of cervical cancer or treatment for cervical precancer or a hysterectomy, and were not planning to move outside of the study area. Women were screened with HPV DNA testing and cytology. HPV-positive women were referred to colposcopy using a standardised protocol, including biopsy collection of observed lesions, endocervical sampling for transformation zone (TZ) type 3, and treatment as needed. Women with initial normal colposcopy or no high-grade cervical lesions on histology (less than cervical intraepithelial neoplasia [CIN] grade 2) were recalled after 18 months for another HPV test to complete disease ascertainment; HPV-positive women were referred for a second colposcopy with biopsy and treatment as needed. Diagnostic accuracy of colposcopy was assessed by considering a positive test result when the colposcopic impression at the initial colposcopy was positive minor, positive major, or suspected cancer, and was considered negative otherwise. The main study outcome was histologically confirmed CIN3+ (defined as grade 3 or worse) detected at the initial visit or 18-month visit. FINDINGS: Between Dec 12, 2012, and Dec 3, 2021, 42 502 women were recruited, and 5985 (14·1%) tested positive for HPV. 4499 participants with complete disease ascertainment and follow-up were included in the analysis, with a median age of 40·6 years (IQR 34·7-49·9). CIN3+ was detected in 669 (14·9%) of 4499 women at the initial visit or 18-month visit (3530 [78·5%] negative or CIN1, 300 [6·7%] CIN2, 616 [13·7%] CIN3, and 53 [1·2%] cancers). Sensitivity was 91·2% (95% CI 88·9-93·2) for CIN3+, whereas specificity was 50·1% (48·5-51·8) for less than CIN2 and 47·1% (45·5-48·7) for less than CIN3. Sensitivity for CIN3+ significantly decreased in older women (93·5% [95% CI 91·3-95·3] in those aged 30-49 years vs 77·6% [68·6-85·0] in those aged 50-65 years; p<0·0001), whereas specificity for less than CIN2 significantly increased (45·7% [43·8-47·6] vs 61·8% [58·7-64·8]; p<0·0001). Sensitivity for CIN3+ was also significantly lower in women with negative cytology than in those with abnormal cytology (p<0·0001). INTERPRETATION: Colposcopy is accurate for CIN3+ detection in HPV-positive women. These results reflect ESTAMPA efforts in an 18-month follow-up strategy to maximise disease detection with an internationally validated clinical management protocol and regular training, including quality improvement practices. We showed that colposcopy can be optimised with proper standardisation to be used as triage in HPV-positive women.

Performance of visual inspection of the cervix with acetic acid (VIA) for triage of HPV screen-positive women: results from the ESTAMPA study.

VIA is recommended for triage of HPV-positive women attending cervical screening. In the multicentric ESTAMPA study, VIA performance for detection of cervical intraepithelial neoplasia grade 3 or worse (CIN3+) among HPV-positive women was evaluated. Women aged 30-64 years were screened with HPV testing and cytology and referred to colposcopy if either test was positive. At colposcopy visit, study-trained midwives/nurses/GPs performed VIA ahead of colposcopy. VIA was considered positive if acetowhite lesions were observed in or close to the transformation zone. Ablative treatment eligibility was assessed for VIA positives. Performance indicators were estimated. Three thousand one hundred and forty-two HPV-positive women were included. Sensitivity for CIN3+ was 85.9% (95% CI 81.2-89.5) among women <50 years and, although not significant, slightly lower in women 50+ (78.0%, 95% CI 65.9-86.6). Overall specificity was 58.6% (95% CI 56.7-60.5) and was significantly higher among women 50+ (70.3%, 95% CI 66.8-73.5) compared to women <50 (54.3%, 95% CI 52.1-56.5). VIA positivity was lower among women 50+ (35.2%, 95% CI 31.9-38.6) compared to women <50 (53.2, 95% CI 51.1-55.2). Overall eligibility for ablative treatment was 74.5% and did not differ by age. VIA sensitivity, specificity, and positivity, and ablative treatment eligibility varied highly by provider (ranges: 25%-95.4%, 44.9%-94.4%, 8.2%-65.3%, 0%-98.7%, respectively). VIA sensitivity for cervical precancer detection among HPV-positive women performed by trained providers was high with an important reduction in referral rates. However, scaling-up HPV screening triaged by VIA will be challenging due to the high variability of VIA performance and providers' need for training and supervision.

Implementing HPV testing in 9 Latin American countries: The laboratory perspective as observed in the ESTAMPA study.

Background: Replacement of cytology screening with HPV testing is recommended and essential for cervical cancer elimination. HPV testing for primary screening was implemented in 12 laboratories within 9 Latin American countries, as part of the ESTAMPA cervical cancer screening study. Our observations provide information on critical operational aspects for HPV testing implementation in diverse resource settings. Methods: We describe the implementation process of HPV testing in ESTAMPA, focusing on laboratory aspects. We assess the readiness of 12 laboratories to start HPV testing and their continuity capacity to maintain good quality HPV testing until end of recruitment or up to December 2021. Readiness was based on a checklist. Information from the study database; regular meetings and monitoring visits; and a questionnaire on laboratory operational aspects sent in May 2020 were used to assess continuity capacity. Compliance with seven basic requirements (readiness) and eight continuity requirements (continuity capacity) was scored (1 = compliant, 0 = not compliant) and totaled to classify readiness and continuity capacity as very limited, limited, moderate or high. Experiences, challenges, and enablers of the implementation process are also described. Results: Seven of 12 laboratories had high readiness, three moderate readiness, and of two laboratories new to HPV testing, one had limited readiness and the other very limited readiness. Two of seven laboratories with high readiness also showed high continuity capacity, one moderate continuity capacity, and the other four showed limited continuity capacity since they could not maintain good quality HPV testing over time. Among three laboratories with moderate readiness, one kept moderate continuity capacity and two reached high continuity capacity. The two laboratories new to HPV testing achieved high continuity capacity. Based on gained expertise, five laboratories have become part of national screening programs. Conclusion: High readiness of laboratories is an essential part of effective implementation of HPV testing. However, high readiness is insufficient to guarantee HPV testing high continuity capacity, for which a "culture of quality" should be established with regular training, robust monitoring and quality assurance systems tailored to local context. All efforts to strengthen HPV laboratories are valuable and crucial to guarantee effective implementation of HPV-based cervical screening.

Distribution of human papillomavirus genotypes by severity of cervical lesions in HPV screened positive women from the ESTAMPA study in Latin America.

The proportion of HPV16 and 18-associated cervical cancer (CC) appears rather constant worldwide (≥70%), but the relative importance of the other HR-HPV differs slightly by geographical region. Here, we studied the HPV genotype distribution of HPV positive Latin American (LA) women by histological grade, in a sub-cohort from the ESTAMPA study; we also explored the association of age-specific HPV genotypes in severe lesions. Cervical samples from 1,252 participants (854 ≤CIN1, 121 CIN2, 194 CIN3 and 83 CC) were genotyped by two PCRs-Reverse Blotting Hybridization strategies: i) Broad-Spectrum General Primers 5+/6+ and ii) PGMY9/11 PCRs. HPV16 was the most frequently found genotype in all histological grades, and increased with the severity of lesions from 14.5% in ≤ CIN1, 19.8% in CIN2, 51.5% in CIN3 to 65.1% in CC (p < 0.001). For the remaining HR-HPVs their frequency in CC did not increase when compared to less severe categories. The nonavalent vaccine HR-types ranked at the top in CC, the dominant ones being HPV16 and HPV45. HR-HPV single infection occurs, respectively, in 57.1% and 57.0% of ≤CIN1 and CIN2, increasing to 72.2% and 91.6% in CIN3 and CC (p<0.001). No association between age and HPV type was observed in CC, although the risk of HPV16 infection in CIN3 cases increased with age. Results confirm the relevance of HPV16 in the whole clinical spectrum, with a strong rise of its proportion in CIN3 and cancer. This information will be relevant in evaluating the impact of HPV vaccination, as a baseline against which to compare genotype changes in HPV type-specific distribution as vaccinated women participate in screening in LA region. Likewise, these data may help select the best HPV testing system for HPV-based efficient, affordable, and sustainable screening programmes.

Reduction in Vaccine HPV Type Infections in a Young Women Group (18-25 Years) Five Years after HPV Vaccine Introduction in Colombia.

In Colombia, the human papillomavirus (HPV) vaccine was launched in 2012 in the context of a school-based national vaccination program targeting girls ages 9 to 14 and offering catch-up vaccination for girls ages 14 to 17. In this study, we evaluated the program's impact on type-specific HPV infection by comparing HPV cervical prevalence among vaccinated and nonvaccinated women. This is a comparative cross-sectional study conducted 5 years after the quadrivalent HPV vaccination implementation in a sentinel Colombian City. This study included young women (18-25 years old) who had been vaccinated in the catch-up group and were attending universities and technical institutions, and women who attended primary health care facilities for Pap smear screening. The HPV prevalence of 1,287 unvaccinated women was compared with the prevalence of 1,986 vaccinated women. The prevalence of HPV16/18 infections was significantly lower in vaccinated compared with unvaccinated women (6.5% vs. 15.4%; P < 0.001), whereas for HPV6/11 infections, a decrease of 63.7% in vaccinated women (1.02% vs. 2.81%) was observed. The adjusted effectiveness to HPV16/18 was 61.4%; 95% CI, 54.3%-67.6%. However, the effectiveness against HPV16/18 was significantly higher among women vaccinated before their sexual debut 91.5%; 95% CI, 86.8-94.5, compared with effectiveness for vaccination after their sexual debut, 36.2%; 95% CI, 23.6-46.7. Five years after the introduction of HPV vaccines in Colombia, high effectiveness of HPV to prevent HPV16/18 infections is observed in the catch-up cohorts including virgin and sexually active women. PREVENTION RELEVANCE: Monitoring HPV vaccines post-licensure plays an important role in assessing the progress of immunization programs, demonstrating the impact of vaccines on the population, and providing data for policy needs. In Colombia, HPV vaccines showed effectiveness when administered before start of sexual activity, and two doses are sufficient to achieve good protection.

Estimation of the Need for Radiation Therapy Services According to the Incidence of Cancer in Colombia to 2035.

PURPOSE: To estimate the supply and demand of current and future radiation therapy services by 2035 for Colombia. METHODS AND MATERIALS: The present study was performed by surveying different radiation therapy services identified in Colombia through the Colombian Association of Radiation Oncology. The demand was estimated based on incident cases and published information on the use of radiation therapy by type of cancer. Future demand was estimated under the assumption that incidence rates do not change and therefore the change in the number of cases is due to the change in the age structure of the Colombian population. Sensitivity analyses were conducted on the percentage of radiation therapy use by type of cancer. A Monte Carlo simulation was carried out to estimate the distribution of cases requiring radiation therapy, the amount of equipment, and the number of staff needed for care with the use of this technology. RESULTS: In total, Colombia has 69 linear accelerators, 2 radiosurgery equipment, 30 high-dose-rate brachytherapy pieces of equipment, 124 radiation therapy oncologists (113 working, 9 not working, and 2 not informed), and 275 radiation therapy technologists as of June 2020. It was estimated that to meet the current cancer burden the country would need a total of 162 radiation therapy oncologists, 121 medical physicists, and 323 radiation therapy technologists and to increase the number of radiation therapy technologists, radiation therapy oncologists, and medical physicists to 491, 246, and 184, respectively, to meet the disease burden by 2035 (73,684-88,743 cases per year). CONCLUSIONS: In Colombia it is estimated that there is a deficit of human resources and technology for radiation therapy; therefore, there is need to investment resources from the public and private sectors to provide timely and quality care to cancer patients requiring this treatment.

Accuracy of combined molecular and morphology-based triage for HPV-positive women in routine cervical cancer screening services from Colombia.

WHO cervical cancer elimination goals comprise 70% of highly-sensitive screening coverage and 90% treatment of precancerous lesions. Triage for HPV-positive women may challenge sensitivity of screening algorithms and women's follow-up, particularly in low- and middle-income countries (LMIC) where screening quality and protocol adherence are frequently deficient. We aimed to determine the accuracy of triage for HPV positive women in routine screening services from Colombia by a prospective cross-sectional study. Consecutively, HPV DNA-positive women underwent six triage strategies (conventional cytology, two methods of visual inspection, HPV16/18/45-genotyping, telomerase, and HPV mRNA). Positive triage results underwent regular colposcopy/biopsy in public hospitals. Adjusted sensitivity, specificity, and predictive values for CIN2+/CIN3+ were estimated for stand-alone and combined tests. We explored the impact of triage strategies on referral rates and the complete screening algorithm (screening plus triage). Overall 16,242 women underwent HPV screening and 1789 (11.0%) were HPV-positive. In total, 20.1% of women were lost to follow-up. mRNA showed the highest positivity rate (0.64 among HPV-positive and 0.05 among the total screened cohort), the highest sensitivity (0.94 95%CI 0.75-0.96), and the lowest specificity (0.36 95%CI 0.29-0.43). Parallel testing with HPV-mRNA revealed the highest increase in sensitivity for all triage strategies. Accuracy of cytology and visual inspection differ between screening units but parallel testing with HPV16/18/45 genotyping significantly increased their sensitivity (over 0.80). Morphology-based triage for HPV-positive women remains a suitable alternative for routine practice in LMIC if combined with HPV16/18/45-genotyping; however, point-of-care triage would be preferable to reduce losses to follow-up. HPV-mRNA triage deserves cost-benefit analyses.

Breast cancer in Colombia: a growing challenge for the healthcare system.

AIM: To provide a comprehensive overview of breast cancer in Colombia. METHODS: Data on breast cancer in Colombia are scarce. We present incidence data from population-based cancer registries that represent 4 distinct regions of the country. Other data originate from non-governmental institutions and healthcare providers within Colombia, official sources, expert opinion, Colombian legislation, and the Cancer Mortality Atlas publishes by Colombian National Cancer Institute. RESULTS: In Colombia, the age-standardized incidence rate remained relatively stable between 2012 and 2020 (43.1 to 47.8 cases per 100,000 women-years); Additionally, survival since 1995 has presented a substantial improvement from 65.7 to 72.1. In 33% of cases, the diagnosis of breast cancer was made in advanced stages, stage III or higher. The health demography survey conducted in 2015 showed that the participation in mammography screening in women aged 40 to 69 remains low 48.1%. Some limitations regarding access to early detection and diagnosis include economic strata, health insurance coverage, origin, and accessibility. On average, a 90-day period was reported from onset of symptoms to diagnosis of breast cancer. CONCLUSION: The first action towards improving outcomes in breast cancer should be to improve stage at diagnosis and timely access to care.

Políticas basadas en la evidencia científica: El caso del control del cáncer de mama en Colombia / Evidence-based policies: The case of breast cancer control in Colombia

Resumen Colombia tiene un riesgo intermedio a desarrollar cáncer de mama con una tasa de incidencia estandarizada por edad en de 44,1 por 100.000 mujeres. A pesar de que en el país se recomienda la tamización mediante mamografía, en mujeres de 50 a 69 años y examen clínico de mama anual, así como detección temprana para mujeres sintomáticas independientemente de la edad; en Colombia no se ha podido reducir la mortalidad por esta causa. Múltiples causas parecen explicar este problema: baja participación en las actividades de tamización con mamografía por parte de la población objeto; baja calidad de la mamografía, y barreras de acceso para el diagnóstico oportuno y el tratamiento integral. Frente a esta problemática el 3 de octubre fue aprobado en primer debate el proyecto de ley 259 de 2019 Cámara Proyecto de Ley "Por medio de la cual se establecen medidas para la prevención, diagnóstico, tratamiento oportuno, rehabilitación, y cuidados paliativos del cáncer de mama y se dictan otras disposiciones". A fin de revisar el soporte científico del contenido del proyecto de ley y aportar a su adecuada discusión, el Instituto Nacional de Cancerologia (INC) realizó un foro el 9 de diciembre de 2019. El propósito de este artículo es presentar el análisis de los puntos de mayor controversia desde una perspectiva científica, como base para la adecuada toma de decisiones en materia de políticas de salud pública.

Abstract Colombia ranks at an intermediate risk level regarding the development of breast cancer, with an age-standardized incidence rate of 44.1 per 100,000 women. Although mammography screening and annual Clinical Breast Examination for women aged 50 to 69 are recommended in Colombia, as well as early detection for symptomatic women regardless of age, mortality from this cause has not been reduced in Colombia. Multiple causes seem to explain this problem: low participation of the target population in mammography screening activities, poor quality of mammography, and access barriers for timely diagnosis and comprehensive treatment. In view of this problem, the House of Representatives approved in first debate last October 3 Bill No. 259 of 2019 "by means of which measures and other provisions for prevention, diagnosis, timely treatment, rehabilitation, and palliative care of breast cancer are set up". The Colombian National Cancer Institute INC, held a forum on December 9, 2019, aimed at reviewing the scientific support of the content of the bill and contribute to its proper discussion. The purpose of this paper is to present the analysis of the most controversial points from a scientific perspective, as a basis for appropriate decision-making in public health policy.

Prevention and control of HPV infection and HPV-related cancers in Colombia- a meeting report.

The Human Papillomavirus (HPV) Prevention and Control Board is an independent multidisciplinary board of international experts that disseminates relevant information on HPV to a broad array of stakeholders and provides guidance on strategic, technical and policy issues in the implementation of HPV control programs. In response to drastic drop of vaccine coverage following the adverse event crisis in Carmen del Bolivar, Colombia, the HPV Prevention and Control Board in collaboration with the Colombian National Cancer Institute and Colombian League Against Cancer convened a meeting in Bogota, Columbia (November 2018). The goal of the meeting was to bring together national and international group of experts to report the disease burden, epidemiology and surveillance of HPV and HPV-related cancers, to discuss the successes and especially the challenges of HPV vaccination and screening in Colombia, as well as the lessons learnt from neighbouring countries. The meeting provided a platform to confer various stakeholder's perspectives, including the role of the Colombian healthcare system and to catalyse various parts of the public health community in Colombia into effective action. The conclusion of the meeting included following suggestions to strengthen HPV prevention and control: 1) Re-introducing school-based vaccine programs, 2) Integrating primary and secondary prevention programs, 3) Developing an innovative crisis communication plan targeting healthcare workers, teachers and general population, 4) Building trust through efficient and timely communication, 5) Building strong relationship with media to ensure a stable vaccination campaign support, and 6) Promoting empathy among healthcare professionals towards patients to build trust and communicate effectively.

Multicentric study of cervical cancer screening with human papillomavirus testing and assessment of triage methods in Latin America: the ESTAMPA screening study protocol.

INTRODUCTION: Human papillomavirus (HPV) testing is replacing cytology in primary screening. Its limited specificity demands using a second (triage) test to better identify women at high-risk of cervical disease. Cytology represents the immediate triage but its low sensitivity might hamper HPV testing sensitivity, particularly in low-income and middle-income countries (LMICs), where cytology performance has been suboptimal. The ESTAMPA (EStudio multicéntrico de TAMizaje y triaje de cáncer de cuello uterino con pruebas del virus del PApiloma humano; Spanish acronym) study will: (1) evaluate the performance of different triage techniques to detect cervical precancer and (2) inform on how to implement HPV-based screening programmes in LMIC. METHODS AND ANALYSIS: Women aged 30-64 years are screened with HPV testing and Pap across 12 study centres in Latin America. Screened positives have colposcopy with biopsy and treatment of lesions. Women with no evident disease are recalled 18 months later for another HPV test; those HPV-positive undergo colposcopy with biopsy and treatment as needed. Biological specimens are collected in different visits for triage testing, which is not used for clinical management. The study outcome is histological high-grade squamous intraepithelial or worse lesions (HSIL+) under the lower anogenital squamous terminology. About 50 000 women will be screened and 500 HSIL+ cases detected (at initial and 18 months screening). Performance measures (sensitivity, specificity and predictive values) of triage techniques to detect HSIL+ will be estimated and compared with adjustment by age and study centre. ETHICS AND DISSEMINATION: The study protocol has been approved by the Ethics Committee of the International Agency for Research on Cancer (IARC), of the Pan American Health Organisation (PAHO) and by those in each participating centre. A Data and Safety Monitoring Board (DSMB) has been established to monitor progress of the study, assure participant safety, advice on scientific conduct and analysis and suggest protocol improvements. Study findings will be published in peer-reviewed journals and presented at scientific meetings. TRIAL REGISTRATION NUMBER: NCT01881659.

Psycho-social impact of positive human papillomavirus testing in Jujuy, Argentina results from the Psycho-Estampa study.

Human papillomavirus (HPV) testing can have a negative impact on women's lives which might also result in abandoning the follow-up and treatment process. This study measured the psycho-social impact of HPV-positivity among HPV-tested women from Jujuy, Argentina, a middle-low income setting. In this cross-sectional study (2015-2016), the psycho-social impact of HPV-positivity was measured using the Psycho-Estampa Scale, specifically designed and validated to be used in screening contexts. We measured mean scores for each of the five scale domains, and the Overall Impact score (Values from 1: No impact to 4: Heavy impact). We compared scores according to cytology triage diagnosis using ordinal logistic regression. A total of 163 HPV-positive women were recruited at the Centro Carlos Alvarado hospital and included in the study sample; of these, 124 (76.1%) had normal triage cytologies. The overall Impact score was between low and moderate (mean:2.56, SD:0.65). The highest psycho-social impact was measured in the Worries about cancer and treatment domain (mean score:3.60, SD:0.60), followed by Sexuality domain (mean:2.50; SD:1.00). The Uncertainty about information provided by health providers domain had the lowest mean score (mean:2.14, SD:0.73). Compared to women with normal cytologies (n = 124), women with abnormal cytologies (n = 39) had a higher likelihood of greater overall Psycho-social Impact (OR: 2.91; p = 0.0036). No statistically significant differences were found in scores of specific domains according to cytology results. It is important to devise specific counseling interventions to reduce the psycho-social impact of HPV-Testing as primary screening and its potential effect on completion of the diagnosis/ treatment process.

Importancia del acceso de los registros de cáncer de base poblacional a las estadísticas vitales: barreras identificadas en Colombia / Importance of access of population-based cancer registries to vital statistics: barriers identified in Colombia

Resumen Los registros de cáncer de base poblacional (RCBP) son los responsables del reporte de incidencia, mortalidad y supervivencia de los pacientes con cáncer para sus respectivas poblaciones. Los RCBP del país son definidos por la legislación colombiana como fuentes de información de los registros nacionales de cáncer para adultos y niños, pero carecen de un soporte jurídico que permita el acceso a las fuentes oficiales de información nacional y enfrentan restricciones dadas por la ley para el tratamiento de datos personales que impide la transferencia de información de los registros nacionales de cáncer y todas sus fuentes hacia los RCBP. Se analizarán los problemas de acceso a la información de estadísticas vitales del país, así como las consecuencias de estas barreras de acceso para los RCBP, y se presentarán argumentos que sustenten la necesidad de que los RCBP puedan acceder a la información necesaria para poder cumplir su objetivo.

Abstract Population-based cancer registries (PBCR) are responsible for reporting incidence, mortality and survival for cancer patients in their respective populations. Colombian legislation assigned the PBCR as sources of information for the national observatory on cancer. However, the PBCR lack legal support that officially assures access to official sources of national vital statistics and information on healthcare consumption; they face restrictions provided by law for the processing of personal data that prevents the transfer of information from national cancer databases and all their sources to the PBCR. We provide analysis of the problems of access to information on vital statistics of the country and the consequences of these access barriers for the PBCR, the presented arguments illustrate the need for the PBCR to have a smooth access to such information to be able to comply with their objectives.

Educación en Colombia para la detección temprana del cáncer de mama / Education for the early detection of breast cancer in Colombia

Introducción. El cáncer de mama representa un problema de salud pública cada vez mayor en Colombia. La mayoría de los estudiantes de medicina y de los profesionales de la salud no reciben capacitación para la detección temprana del cáncer de mama. Objetivo. Describir el proceso llevado a cabo por el Instituto Nacional de Cancerología de Colombia, para capacitar a los profesionales de la salud (médicos generales, ginecólogos, médicos familiares y enfermeras) en la detección temprana del cáncer de mama, mediante cursos presenciales y virtuales. Resultados. Con las dos modalidades de cursos, 1.875 profesionales de la salud han sido capacitados, la mayoría de ellos mediante el curso virtual (n=1.294; 73,0 %). Asimismo, los médicos generales han sido los profesionales que más se han certificado mediante alguna de las dos modalidades del curso (n=919; 49,0 %). Los dos cursos generan gran satisfacción en los participantes, con una tasa de certificación del 100 % en la modalidad presencial y del 73,0 % en la virtual. Conclusiones. Es difícil medir el impacto de la capacitación profesional en el diagnóstico precoz del cáncer de mama, porque la mayoría de las regiones de Colombia no tienen registros de cáncer. Es probable que, con un tiempo mayor de seguimiento, se logre medir el impacto real de los cursos en la detección temprana del cáncer de mama y, por ende, en la mortalidad debida a la enfermedad (AU)

Introduction: Breast cancer represents an increasing public health issue in Colombia. Most undergraduate medical students and health professionals do not receive training in early detection of breast cancer. Material and methods: This article describes the process and achievements developed by the National Cancer Institute of Colombia (NCIC) to train health professionals (general practitioners [GP], gynecologists, family doctors and chief nurses) in early detection of breast cancer through two modalities courses: physical presence and virtual. Results: With these two course modalities 1,875 health professionals have been trained, most of them were certified through the virtual course (n=1.294; 73,.0 %). Most of the trained health professionals were GP (n=919; 49,0 %). Both modalities had a high level of satisfaction of the participants, a certification rate of 100 % in the face-to-face modality and 73.0 % in the virtual one. Conclusions: It is difficult to measure the impact of professional training in the clinical staging of breast cancer mainly because most regions in Colombia do not have cancer records. We should have a longer follow-up time to be able to measure the real impact in achieving lower clinical staging and, therefore, to reduce mortality due to the disease (AU)
